Inventor: IIJIMA TAIZO
IPC: G06V10/75
Filed: 1974-08-08
Abstract: As reference patterns belonging to any one of categories, M number of reference patterns satisfying an orthonormal relation to each other and N number of reference patterns having an orthonormal relation to each of the M number of reference patterns and satisfying an orthogonal relation to each other are prepared. Whether or not a category-unknown input pattern belongs to a specified category is determined dependent upon whether or not a difference between the sum of squares of values each representing the similarity of the input pattern to each of M number of reference patterns and the sum of squares of values each representing the similarity of the input pattern to each of N number of reference patterns is greater than a predetermined threshold value.

Patent DE-2453766-A1 (DE)
Title: Tubular heating elements of specified length - are produced by reduction of tube diameter in several operations
Inventor: KOPKA ERHARD
IPC: H05B3/52
Filed: 1974-11-13
Abstract: The heating tube contains a resistor of spiral shape which is used as the heating element, and this element is embedded in an insulating powder. The diameter of the tube may be reduced by circular hammering, rolling etc; and this process causes an increase in length. The difference between actual and required length is measured, and the cross section reduction is adjusted accordingly. When the heating element passes through the last stage, the tube length increase is continuously measured, and the cross-section reduction is automatically stopped when the length increase has reached the required value.

Title: Power press safety mechanism for protection of operators - punch may not be actuated until guard cover clears tool to trip limit sensor
Inventor: BORN GUSTAV ADOLF
IPC: F16P3/04
Filed: 1974-11-19
Abstract: A safety control mechanism for power presses dispenses with the need for a moving guard screen and utilises a cylinder actuated cover plate directly over the tool set. With the punch (1) in the top position a cover plate (4) guided in a tenon slot in the bottom tool (6), is located directly over hole (5) in the base. A pneumatic cylinder (12) front mounted onto an angled mounting bracket (14) has the piston rod (11) secured to the cover plate. The cover plate is moved between the guard position and the stop block (17). Two limit sensors provide signals at the extreme ends of cylinder motion. In operation the punch cannot be actuated until the limit sensor indicating a fully retracted cover has been tripped.

Patent DE-2517132-A1 (DE)
Title: Multi-strand wire electrical conductor - comprises a coated core wire and outer wires adhering to the coating
Inventor: ERNST JUERGEN
IPC: H01B7/30
Filed: 1975-04-18
Abstract: A stranded wire conductor comprises a thermoplastic-coated core wire surrounded by outer wires that adhere to the thermoplastices coating. The undesirable (and sometimes unnoticed) 'fanning-out' of the outer wires during mounting and connecting e.g. onto a circuit that can cause shorting or wrong connections is avoided. Once the outermost insulation is stripped, the outer wires cannot 'stand away' from the wire bundle as a whole. No tin-coating is required, hence high flexibility.

Title: Sorter for separating potatoes from earth - has intermeshing elastic bristled conveyor and rollers
Inventor: QUAST OTTO P
IPC: B07B13/00
Filed: 1975-08-08
Abstract: The machine is for sorting of root vegetables esp. potatoes, from stones and soil. There is a loop conveyor and an array of roller brushes with elastic bristles. The bristles (6) of each roller are bent backwards by contact with the other intermeshing bristled rollers (1, 2, 3, 10). The density and elasticity of the bristles are selected so that the root vegetable and gangue are separated gravitationally. The fine material and stones fall through the intermeshing bristles. All the rollers rotate in the same direction so that the meshing bristles interfere with each other as they move in opposite directions.

Title: Sliding vane type rotary compressor - is unloaded by axial movement of cylinder to form bypass
Inventor: HILDEBRANDT ERICH
IPC: F04C28/26
Filed: 1975-10-01
Abstract: The compressor has a cylindrical casing (1) with two end caps (5, 6). A rotor (2) is carried on a shaft (3) eccentrically in the casing. It has radial slots (4) in which spring loaded vanes reciprocate with their outer ends pressing against the inside of the casing so that they separate variable volume working spaces between them. In normal operation the cylinder end caps (5, 6) are tight against the rotor end faces so that gas cannot leak from one side of the rotor to the other. One or both end caps can slide axially within the casing. When it moves away from the rotor it leaves a passage (8) at the side of the rotor through which gas flows from the discharge back to the suction side.

Title: Radially compressible yarn stabilising or fixing bobbin - has part of its periphery formed by axially extending castellated segment permitting controlled yarn shrinking
Inventor: SCHUERMANN HEINER
IPC: B65H75/24
Filed: 1976-03-06
Abstract: Radially compressible yarn bobbin has part of its circumference provided with an axially extending castellated segment. Cylindrical or frusto-conical bobbins can be obtd. for fixing and stabilising yarns. Pref. the bobbin is injection moulded from a plastics material and the segment is formed by interdigited prongs which are slidable along the inner surface of the bobbin between two end positions which determine the diametral dimensions of the compressible bobbin. End positions are defined by end stops and the bobbin retains its circular cross-section and uniform axial configuration over its whole length. Shrinkage of yarns can be controlled to the desired value whilst the cross-sectional area of the bobbin remains circular, whereby bobbin may be used directly on subsequent processing machines.
